English TROUBLESHOOTING Problem The display became blank. The battery life indicator is shown. The battery life indicator is flashing. The watch gains/loses occasionally. A blur inside the glass persists. Three altitude rank indicator bars are flashing. The number of residual nitrogen indicator bars on the display increased while on the surface. The number of residual nitrogen indicator bars on the display increased during flight. The display will not return to the TIME/CALENDAR after diving. The dive function was shown while on the surface, and a depth of more than 1.5 m (5 ft) was displayed. The dive function will not start. Possible cause The battery has run down. The battery is nearing its end. The watch was left in low or high temperatures. The gasket is deteriorated, and water got inside the watch. Unless you are at an altitude over 6,000 m (19,700 ft), the pressure sensor is out of order. You moved to a higher altitude across the altitude ranks. The atmospheric pressure inside airplanes corresponds to altitude rank "2", and the watch has re-calculated the altitude. Water remains on the auto switch. Water remains on the auto switch, or the auto switch was turned on during flight and the airplane landed. A dive beyond the specified limit was made within the past 48 hours. The battery life indicator is lighting up or flashing. Three altitude rank indicator bars are flashing. Solution Take the watch to the retailer from whom it was purchased immediately for battery replacement. ** The accuracy will be corrected when the watch returns to normal temperature. Set the time before using the watch. It is so adjusted that it operates with stable accuracy when used on the wrist within a temperature range between 5° C and 35° C (41° F and 95° F). Consult the retailer from whom it was purchased. The watch senses the atmospheric pressure change and recalculates residual nitrogen. The obtained residual nitrogen will be taken into consideration in calculations in the dive plan function. Wipe the auto switch with a dry cloth. Make sure that the auto switch is always clean and dry. In a place such as inside an airplane where the atmospheric pressure changes sharply, take utmost care not to leave the auto switch wet. Do not use the watch for diving for 48 hours. Take the watch to the retailer from whom it was purchased immediately for battery replacement. The watch cannot be used for diving at an altitude over 6,000 m (19,700 ft). Unless you are at an altitude over 6,000 m, the pressure sensor is out of order. Consult the retailer from whom it was purchased. 28 English Problem The watch calculates decompression diving even after a dive. Possible cause The diver ascended defying the decompression stop violation warning. Solution When the surface interval time is less than 5 minutes, making a decompression stop as indicated by the watch will return the display for no-decompression diving. **The log data stored in the dive log function will not be erased when the battery is replaced with a new one. If any malfunction is found during checking, however, the stored log data may be erased when the watch is repaired. It is recommended that the log data in memory be noted down in your log book before requesting a battery change.
